Detailed Implementation

[0028] The attached figure shows a preferred embodiment of an electric vehicle riding assistance device with a tire height adjustment mechanism. The present application will be further described in detail below with reference to the attached figure.

[0029] An electric vehicle riding assistance device with a tire height adjustment mechanism, consisting of... Figures 1 to 4 As shown, it includes the auxiliary wheel assembly.

[0030] The auxiliary wheel assembly includes an auxiliary wheel 1, which is rotatably connected to a connecting frame 2. The connecting frame 2 is hinged to a fixed frame 3 via a hinge plate 4. A shock absorber 7 is provided between the connecting frame 2 and the fixed frame 3.

[0031] The fixed frame 3 is provided with a first fixed plate 301 on the end face away from the auxiliary wheel 1, and the first fixed plate 301 is provided with a plurality of first through holes 302.

[0032] Since an electric vehicle needs to be equipped with two auxiliary wheel assemblies to better ensure its stability, in this embodiment, to ensure that the auxiliary wheels on both sides are installed at the same height, the two auxiliary wheel assemblies are fixedly connected by a mounting bracket 9. The mounting bracket 9 includes a straight tube 901 and a second fixing plate 902 fixedly connected to both ends of the straight tube 901. The hole on the second fixing plate 902 is fixedly connected to the first through hole 302 by bolts, and the straight tube 901 is attached to the electric vehicle.

[0033] The number of holes on the second fixing plate 902 is less than the number of first through holes 302 on the first fixing plate 301, so that the connection height between the auxiliary wheel assembly and the bracket 9 can be adjusted.

[0034] The top side of the fixing frame 3 is provided with a third through hole 304, and a disconnector 8 is inserted inside the third through hole 304. The disconnector 8 is a pull ring pin.

[0035] The connecting frame 2 is provided with a connecting shaft 6, and the through holes at both ends of the shock absorber 7 are respectively fitted onto the connecting shaft 6 and the disconnector 8.

[0036] The fixing frame 3 has a second through hole 303 located below the third through hole 304. A triangular plate 5 is provided between the connecting frame 2 and the fixing frame 3. The triangular plate 5 is rotatably connected to the connecting shaft 6.

[0037] The triangular plate 5 is provided with a hanging hole 501, a fourth through hole 502 and a fifth through hole 503 arranged in a triangular pattern.

[0038] The fifth through hole 503 is rotatably connected to the connecting shaft 6, and the fourth through hole 502 is coaxially arranged with the second through hole 303. The two are rotatably connected by a rotating shaft.

[0039] The hole spacing between the mounting hole 501 and the fourth through hole 502 is the same as the hole spacing between the second through hole 303 and the third through hole 304.

[0040] When road conditions are good, the training wheel 1 needs to be lifted to reduce riding resistance. The procedure for lifting the training wheel 1 is as follows: remove the disconnector 8, separate the shock absorber 7 from the disconnector 8, and then rotate it to rest against the inside of the training wheel 1. Then rotate the hinge plate 4 and the triangle plate 5, thereby moving the connecting frame 2 and the training wheel 1 upwards, thus lifting the training wheel.

[0041] Since the hole spacing between the mounting hole 501 and the fourth through hole 502 is the same as the hole spacing between the second through hole 303 and the third through hole 304, the triangle plate 5 is rotated to a position where the mounting hole 501 and the third through hole 304 are arranged coaxially. Then, the disconnector 8 is inserted between the mounting hole 501 and the third through hole 304 to fix the triangle plate 5, thereby fixing the raised auxiliary wheel 1.

[0042] To prevent the shock absorber 7 from shaking, the connecting frame 2 or the fixing frame 3 is provided with a detachable limiter 10. The limiter 10 clamps the shock absorber 7, after it is detached from the disconnector 8, between the auxiliary wheels 1. The limiter 10 can be a locking block, a locking ring, or a clamp.

[0043] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
